如何在friendsofsymfony/rest bundle v3中以json格式显示所有错误

Question

我想要截取Symfony的所有错误，然后将它们显示在JSON中。在symfony/rest bundle v2的朋友中，我可以设置参数

fos_rest:
exception:
enabled: true
exception_controller: 'AppControllerExceptionController::showAction'
...

但在V3中，参数exception_controller被删除。

我当前的FOS REST:配置

fos_rest:
view:
formats:
xml:  false
json: true
view_response_listener: force
serializer:
groups: ['Default']
serialize_null: true
format_listener:
rules:
- { path: ^/api/v1, priorities: [ json ], fallback_format: json, prefer_extension: true }
exception:
enabled: true

官方手册说应该在JMS中使用处理程序。https://symfony.com/doc/current/bundles/FOSRestBundle/4-exception-controller-support.html但它并没有包含如何在yaml中设置config的解释。

您可以通过symfony订阅者拦截所有错误

<?php
declare(strict_types=1);
namespace AppUtilSerializerNormalizer;
use JMSSerializerContext;
use JMSSerializerGraphNavigatorInterface;
use JMSSerializerHandlerSubscribingHandlerInterface;
use JMSSerializerJsonSerializationVisitor;
use SymfonyComponentHttpFoundationResponse;
use SymfonyComponentSerializerEncoderJsonEncoder;
class CustomExceptionHandler implements SubscribingHandlerInterface
{
private bool $debug;
public function __construct(bool $kernelDebug)
{
$this->debug = $kernelDebug;
}
public static function getSubscribingMethods(): array
{
return [
[
'direction' => GraphNavigatorInterface::DIRECTION_SERIALIZATION,
'format'    => JsonEncoder::FORMAT,
'type'      => Exception::class,
'method'    => 'serializeToJson',
'priority'  => -1,
],
];
}
public function serializeToJson(
JsonSerializationVisitor $visitor,
Exception $exception,
array $type,
Context $context
) {
$data = $this->convertToArray($exception, $context);
return $visitor->visitArray($data, $type);
}
/**
* @return array<string, mixed>
*/
protected function convertToArray(Exception $exception, Context $context): array
{
$statusCode = null;
if ($context->hasAttribute('template_data')) {
$templateData = $context->getAttribute('template_data');
if (array_key_exists('status_code', $templateData)) {
$statusCode = $templateData['status_code'];
}
}
$data['error'] = $this->getMessageFromThrowable($exception, $statusCode);
return $data;
}
protected function getMessageFromThrowable(Throwable $throwable, ?int $statusCode): string
{
if ($this->debug) {
return $throwable->getMessage();
}
return array_key_exists($statusCode, Response::$statusTexts) ? Response::$statusTexts[$statusCode] : 'error';
}
}
